I've used super zooms, but never that one. It is supposedly very good for a super zoom. I have used other super zooms, and never liked them. I think that you will definitely lose IQ in the 28-70mm range, but either stay equal or possibly gain a little IQ in the 71-300mm range compared to your current lenses.
i would say that i find myself using the 24-70 a lot more than the 70-300. so i would say that's a little concerning. the 70-300 is usually for the fast moving shots around the track (car races). given i now have a 1 year old kid i don't get out much to the track
Im not sure if people who commented in this thread have actually experience with 28-300mm lens, I meant a real experience not just testing in the store or used other peoples lens. I used to have it for a while and along with 1d4 was my walk around rig. Yes it is very heavy and thats the ony problem. I sold my 24-70mm to get this lens. The IQ was amazing thruout the range and it was sharp too
a little contradicting to the other statement. i really need to find somebody with this lens and test it out, to see if i like it better.
the weight issue is a little concerning for my overseas trips. the 24-70 does get tiring on an all day walks. can't image if the 28-300 is double the weight.
decisions, decisions, decisions...
